Figure 6-31 Binary selection of the fixed speed setpoint
Example
After it has been switched on, a conveyor belt only runs with two different velocities. The motor
should now operate with the following corresponding speeds:
● The signal at digital input 0 switches the motor on and accelerates it up to 300 rpm.
● The signal at digital input 1 accelerates the motor up to 2000 rpm.
● With signals at both digital inputs, the motor accelerates up to 2300 rpm.
Table 6-33 Settings for the application example
Parameter Description
p1001[0] = 300.000 Fixed speed setpoint 1 [rpm]
p1002[0] = 2000.000 Fixed speed setpoint 2 [rpm]
p0840[0] = 722.0 ON/OFF1: Switches on the motor with digital input 0
p1070[0] = 1024 Main setpoint: Interconnects the main setpoint with a fixed speed setpoint.
p1020[0] = 722.0 Fixed speed setpoint selection, bit 0: Interconnects fixed speed setpoint 1
with digital input 0 (DI 0).
p1021[0] = 722.1 Fixed speed setpoint selection, bit 1: Interconnects fixed speed setpoint 2
with digital input 1 (DI 1).
p1016 = 1 Fixed speed setpoint mode: Directly selects fixed speed setpoints.
Table 6-34 Resulting fixed speed setpoints for the application example
Fixed speed setpoint selected via Resulting setpoint
DI 0 = 0 Motor stops
DI 0 = 1 and DI 1 = 0 300 rpm
DI 0 = 1 and DI 1 = 1 2300 rpm
